Oh Please let his space craft run out of fuel and drift off into space never to be recovered...
Sorry, can't.
The spacecraft is going straight up, and will not have enough speed to escape the Earth's gravity. It will come straight back down, as it's designed to do.
The thing is, every test Blue Origin has done with New Shepard has been 100% perfect. Yes, I'll grant you that there's always the possibility of an equipment malfunction, but with actual passengers aboard, you know darn well they're going to triple-check everything, especially since thousands will be watching live on the Internet.
The most-likely cause of a problem may indeed be sabotage.
(Now, if you really want to go full-blown conspiracy-nut theory, try this on for size: He goes up there and something does happen, and they're all killed, live on YouTube. In the 'investigation' it's found that an 'employee shot himself' right after the incident. His apartment is searched, and found chock-full of American flags, conservative and Christian literature, and posters of...you guessed it...President Trump with "Trump 2024" flags all over the place. Can you guess what'd happen after that?)
